Uusien uhkakuvien luominen: tapaus 'kiinalaiset kybersoturit' : lingvistinen uhka-analyysi kyberdiskurssista

Since his inauguration, President Barack Obama has emphasized the need for a new cybersecurity policy, pledging to make it a "national security priority". This is a significant change in security discourse after an eight-year war on terror – a term Obama announced to be no longer in use. After several white papers, reports and the release of the so-called 60-day Cybersecurity Review, Obama announced the creation of a "cyber czar" position and a new military cyber command to coordinate American cyber defence and warfare. China, as an alleged cyber rival, has played an important role in the discourse that introduced the need for the new office and the proposals for changes in legislation. Research conducted before this study suggest the dominance of state-centric enemy descriptions paused briefly after 9/11, but returned soon into threat discourse. The focus on China's cyber activities fits this trend. The aim of this study is to analyze the type of modern threat scenarios through a linguistic case study on the reporting on Chinese hackers. The methodology of this threat analysis is based on the systemic functional language theory, and realizes as an analysis of action and being descriptions (verbs) used by the American authorities. The main sources of data include the Cybersecurity Act 2009, Securing Cyberspace for the 44th Presidency, and 2008 Report to Congress of the U.S. - China Economic and Security Review Commission. Contrary to the prevailing and popularized terrorism discourse, the results show the comeback of Cold War rhetoric as well as the establishment of a state-centric threat perception in cyber discourse. Cyber adversaries are referred to with descriptions of capacity, technological superiority and untrustworthiness, whereas the ‘self’ is described as vulnerable and weak. The threat of cyber attacks is compared to physical attacks on critical military and civilian infrastructure. The authorities and the media form a cycle, in which both sides quote each other and foster each other’s distrust and rhetoric. The white papers present China's cyber army as an existential threat. This leads to cyber discourse turning into a school-book example of a securitization process. The need for security demands action descriptions, which makes new rules and regulations acceptable. Cyber discourse has motives and agendas that are separate from real security discourse: the arms race of the 21st century is about unmanned war.

Dry months in the agricultural region of Ribeirão Preto, state of São Paulo-Brazil: an study based on the extreme value theory

The application of the Extreme Value Theory (EVT) to model the probability of occurrence of extreme low Standardized Precipitation Index (SPI) values leads to an increase of the knowledge related to the occurrence of extreme dry months. This sort of analysis can be carried out by means of two approaches: the block maxima (BM; associated with the General Extreme Value distribution) and the peaks-over-threshold (POT; associated with the Generalized Pareto distribution). Each of these procedures has its own advantages and drawbacks. Thus, the main goal of this study is to compare the performance of BM and POT in characterizing the probability of occurrence of extreme dry SPI values obtained from the weather station of Ribeirão Preto-SP (1937-2012). According to the goodness-of-fit tests, both BM and POT can be used to assess the probability of occurrence of the aforementioned extreme dry SPI monthly values. However, the scalar measures of accuracy and the return level plots indicate that POT provides the best fit distribution. The study also indicated that the uncertainties in the parameters estimates of a probabilistic model should be taken into account when the probability associated with a severe/extreme dry event is under analysis.

CORPORATE SOCIAL RESPONSIBILITY from theory into financial statement: UPM-Kymmene Oyj

For number of reasons social responsibility in corporations has become a more essential part of business operations than before. Corporate social responsibility (CSR) is dealt with different means and aspects but the overall effects it has on organisations performance, communication and underline actions is indisputable. The thesis describes corporate social responsibility and the main objective was to observe how corporate social responsibility has developed in our case company with answering to main research question how CSR reporting has evolved in UPM-Kymmene Oyj? In addition following questions were also addressed: Is there a monetary value of CSR? What does proficient CSR report consist of? What does corporate social responsibility consist of? Qualitative research method, content analysis to be precise, was chosen and excessive literature study performed to find the theoretical back ground to perform the empirical part of the study. Data for the empirical part was collected from UPM-Kymmene Oyj financial data and annual reports. The study shows that UPM-Kymmene Oyj engagement to CSR and reporting of CSR matter have improved due time but still few managerial implications could be found. UPM-Kymmene Oyj economic key figures are only building shareholder value and stakeholders are identified in very general level. Also CSR data is scattered all over the annual report which causes problems to readers. The scientific importance of this thesis arises from the profound way CSR has been addressed in a holistic manner. Thus it is giving a good basis to understand the underlying reasons of CSR from society towards the organisation and vice versa.

MASTER DATA MANAGEMENT MATURITY AND TECHNOLOGY ASSESSMENT - From theory to practice, case Ineo Oy

After decades of mergers and acquisitions and successive technology trends such as CRM, ERP and DW, the data in enterprise systems is scattered and inconsistent. Global organizations face the challenge of addressing local uses of shared business entities, such as customer and material, and at the same time have a consistent, unique, and consolidate view of financial indicators. In addition, current enterprise systems do not accommodate the pace of organizational changes and immense efforts are required to maintain data. When it comes to systems integration, ERPs are considered “closed” and expensive. Data structures are complex and the “out-of-the-box” integration options offered are not based on industry standards. Therefore expensive and time-consuming projects are undertaken in order to have required data flowing according to business processes needs. Master Data Management (MDM) emerges as one discipline focused on ensuring long-term data consistency. Presented as a technology-enabled business discipline, it emphasizes business process and governance to model and maintain the data related to key business entities. There are immense technical and organizational challenges to accomplish the “single version of the truth” MDM mantra. Adding one central repository of master data might prove unfeasible in a few scenarios, thus an incremental approach is recommended, starting from areas most critically affected by data issues. This research aims at understanding the current literature on MDM and contrasting it with views from professionals. The data collected from interviews revealed details on the complexities of data structures and data management practices in global organizations, reinforcing the call for more in-depth research on organizational aspects of MDM. The most difficult piece of master data to manage is the “local” part, the attributes related to the sourcing and storing of materials in one particular warehouse in The Netherlands or a complex set of pricing rules for a subsidiary of a customer in Brazil. From a practical perspective, this research evaluates one MDM solution under development at a Finnish IT solution-provider. By means of applying an existing assessment method, the research attempts at providing the company with one possible tool to evaluate its product from a vendor-agnostics perspective.

Elämänkokemukset ja koherenssin tunne – typologinen tutkimus grounded theory -metodologiaa soveltaen

Tutkimuksen tarkoituksena on laadullisin menetelmin syventää tietoa työikäisten (28–60-vuotiaiden) suomalaisten kvantitatiivisesti mitatun koherenssin tunteen takana olevista tekijöistä. Tutkimuksella halutaan tuottaa aineistolähtöisesti tietoa siitä, mitkä käsitteet kuvaavat tutkittavien kerrottujen elämänkokemusten kautta selvitettyä koherenssin tunnetta ja samalla lisäämään ymmärrystä Antonovskyn salutogeenisesta teoreettisesta mallista. Tutkimukseen osallistuneet olivat Health and Social Support tutkimukseen vuosina 1998 ja 2003 osallistuneita. Koko kyseinen tutkimusotos edusti vuonna 1998 20–24, 30–34, 40–44 ja 50–54 -vuotiasta Suomen väestöä. Tutkimuksen metodina käytettiin glaserilaista grounded theory -metodologiaa. Tutkimuksen aineistonkeruu toteutettiin kolmessa eri vaiheessa. Ensimmäisessä vaiheessa haastateltiin 27 tutkittavaa. Toisessa vaiheessa haastateltavilta kerättiin lisäaineistoa kirjallisesti. Kahdeksan vastasi tähän pyyntöön. Kolmannessa vaiheessa haastateltiin seitsemää. Haastattelujen yhteydessä haastateltavat täyttivät koherenssin tunteen mittarin (13-osainen). Aineisto analysoitiin koherenssipisteiden mukaisesti kolmena eri aineistona. Tulokseksi saatiin substantiivinen teoria. Tutkimuksen tuloksena kuvattiin sosiaalinen perusprosessi, joka nimitettiin Elämän kokonaisuudeksi tässä hetkessä. Sosiaalisen perusprosessin sisällä on typologia. Jokaisesta koherenssipisteryhmästä muodostettiin oma typologia. Kukin typologia sisälsi neljä tyyppiä. Sosiaalisen perusprosessin vaiheet olivat: ehdot tämän hetken taustalla, eläminen ehtojen varassa ja uusia luoden (tietynlainen ihminen, eläminen tässä hetkessä, kokonaisnäkemys elämästä) sekä jatkaminen ehtojen varassa ja uusia luoden. Typologiat ovat nimeltään eheät, pärjäävät ja sinnittelijät. Haastateltavien kokemuksia ei analyysivaiheessa pyritty liittämään tiettyyn kontekstiin, vaan ne liittyivät toimintaan ja käyttäytymiseen. Tulosten tarkasteluvaiheessa tehtiin kuitenkin lyhyt kuvaus elämänkulkututkimuksesta sekä sosiaalisesta ja kulttuurisesta ympäristöstä. Tutkimustulokset ovat kuvailevia ja niiden perusteella saadaan viitteitä siitä, millaiset asiat ovat yhteydessä koherenssin tunteeseen ja millä tavalla yhteys rakentuu. Saatu substantiivinen teoria on pätevä tässä aineistossa. Tulokset noudattelevat Antonovskyn salutogeenista teoreettista mallia siltä osin, että mitä korkeammat koherenssipisteet olivat, sitä enemmän typologiassa oli eheyttä lisääviä tekijöitä. Eheys tuo elämään henkistä liikkumavaraa, jota typologian tyypit (rakentava, ilmavasti elävä, elämänmyönteinen, juureva realisti) ilmentävät. Typologioiden kuvauksista voidaan lukea, että kaikissa tyypeissä kuvataan vaikeita elämänkokemuksia. Olennaista on se, miten näihin vaikeuksiin suhtaudutaan. Eheillä on parhaat edellytykset käsitellä elämän haasteita. Voidaan kuitenkin todeta, että kaikki tähän tutkimukseen osallistuneet olivat selviytyjiä.

Social ventures : the development of the theory of sustainable contributive advantage and initial empirical tests

This thesis attempts to fill gaps in both a theoretical basis and an operational and strategic understanding in the areas of social ventures, social entrepreneurship and nonprofit business models. This study also attempts to bridge the gap in strategic and economic theory between social and commercial ventures. More specifically, this thesis explores sustainable competitive advantage from a resource-based theory perspective and explores how it may be applied to the nonmarket situation of nonprofit organizations and social ventures. It is proposed that a social value-orientation of sustainable competitive advantage, called sustainable contributive advantage, provides a more realistic depiction of what is necessary in order for a social venture to perform better than its competitors over time. In addition to providing this realistic depiction, this research provides a substantial theoretical contribution in the area of economics, social ventures, and strategy research, specifically in regards to resource-based theory. The proposed model for sustainable contributive advantage uses resource-based theory and competitive advantage in order to be applicable to social ventures. This model proposes an explanation of a social venture’s ability to demonstrate consistently superior performance. In order to determine whether sustainable competitive advantage is in fact, appropriate to apply to both social and economic environments, quantitative analyses are conducted on a large sample of nonprofit organizations in a single industry and then compared to similar quantitative analyses conducted on commercial ventures. In comparing the trends and strategies between the two types of entities from a quantitative perspective, propositions are developed regarding a social venture’s resource utilization strategies and their possible impact on performance. Evidence is found to support the necessity of adjusting existing models in resource-based theory in order to apply them to social ventures. Additionally supported is the proposed theory of sustainable contributive advantage. The thesis concludes with recommendations for practitioners, researchers and policy makers as well as suggestions for future research paths.

Reflexive Space. A Constructionist Model of the Russian Reflexive Marker

This study examines the structure of the Russian Reflexive Marker ( ся/-сь) and offers a usage-based model building on Construction Grammar and a probabilistic view of linguistic structure. Traditionally, reflexive verbs are accounted for relative to non-reflexive verbs. These accounts assume that linguistic structures emerge as pairs. Furthermore, these accounts assume directionality where the semantics and structure of a reflexive verb can be derived from the non-reflexive verb. However, this directionality does not necessarily hold diachronically. Additionally, the semantics and the patterns associated with a particular reflexive verb are not always shared with the non-reflexive verb. Thus, a model is proposed that can accommodate the traditional pairs as well as for the possible deviations without postulating different systems. A random sample of 2000 instances marked with the Reflexive Marker was extracted from the Russian National Corpus and the sample used in this study contains 819 unique reflexive verbs. This study moves away from the traditional pair account and introduces the concept of Neighbor Verb. A neighbor verb exists for a reflexive verb if they share the same phonological form excluding the Reflexive Marker. It is claimed here that the Reflexive Marker constitutes a system in Russian and the relation between the reflexive and neighbor verbs constitutes a cross-paradigmatic relation. Furthermore, the relation between the reflexive and the neighbor verb is argued to be of symbolic connectivity rather than directionality. Effectively, the relation holding between particular instantiations can vary. The theoretical basis of the present study builds on this assumption. Several new variables are examined in order to systematically model variability of this symbolic connectivity, specifically the degree and strength of connectivity between items. In usage-based models, the lexicon does not constitute an unstructured list of items. Instead, items are assumed to be interconnected in a network. This interconnectedness is defined as Neighborhood in this study. Additionally, each verb carves its own niche within the Neighborhood and this interconnectedness is modeled through rhyme verbs constituting the degree of connectivity of a particular verb in the lexicon. The second component of the degree of connectivity concerns the status of a particular verb relative to its rhyme verbs. The connectivity within the neighborhood of a particular verb varies and this variability is quantified by using the Levenshtein distance. The second property of the lexical network is the strength of connectivity between items. Frequency of use has been one of the primary variables in functional linguistics used to probe this. In addition, a new variable called Constructional Entropy is introduced in this study building on information theory. It is a quantification of the amount of information carried by a particular reflexive verb in one or more argument constructions. The results of the lexical connectivity indicate that the reflexive verbs have statistically greater neighborhood distances than the neighbor verbs. This distributional property can be used to motivate the traditional observation that the reflexive verbs tend to have idiosyncratic properties. A set of argument constructions, generalizations over usage patterns, are proposed for the reflexive verbs in this study. In addition to the variables associated with the lexical connectivity, a number of variables proposed in the literature are explored and used as predictors in the model. The second part of this study introduces the use of a machine learning algorithm called Random Forests. The performance of the model indicates that it is capable, up to a degree, of disambiguating the proposed argument construction types of the Russian Reflexive Marker. Additionally, a global ranking of the predictors used in the model is offered. Finally, most construction grammars assume that argument construction form a network structure. A new method is proposed that establishes generalization over the argument constructions referred to as Linking Construction. In sum, this study explores the structural properties of the Russian Reflexive Marker and a new model is set forth that can accommodate both the traditional pairs and potential deviations from it in a principled manner.

Grounded theory -tutkimusmenetelmä ja sen käyttö akateemisissa julkaisuissa

Työn tavoitteena on selvittää mitä on grounded theory, miten se on sovellettavissa akateemisissa julkaisuissa ja miten eri julkaisujen grounded theory -tutkimukset eroavat toisistaan. Työ on toteutettu järjestelmällisesti analysoimalla neljän markkinointia käsittelevän lehden julkaisemat GT-tutkimukset vuosina 2000-2012. Tuloksina havaitaan lehdille tyypillisiä ominaispiirteitä. Tarkastelun kohteena ovat tutkimusotannat, tutkimusprosessit, tutkimusten aihealueet sekä tutkimuksissa esitetyt lopputulokset. Lisäksi työssä tarkastellaan havaittuja trendejä grounded theory tutkimuksissa sekä pohditaan tutkimusmenetelmän tulevaisuutta. Perinteinen GT-tutkimus on tietyissä akateemisissa lehdissä yhä yleisesti käytetty menetelmä, mutta sen soveltava käyttö, sekä monimenetelmäiset tutkimukset ovat selvässä kasvussa.
